MANUFACTURE OF AXES.

SPECIFICATION forming part of Letters Patent N 0. 444.886, dated January20, 1891.

Application filed October 11,1890. Serial No. 367,798. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES HUBBARD, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in the Manufacture of Axes, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in which--Figure 1 is a plan View of abar of steel rolled into proper form for themanufacture of my improved poll-blank. Fig. 2 is a vertical crosssectionof the bar shown in Fig. 1. Fig. 3 shows the manner in which the severedblank is bent to form the aX-poll.

My invention consistsin a bar of steel rolled into a certain shape incross-section, hereinafter described, and adapted when dividedtransversely to form blanks each of which when benttogether and weldedconstitutes an aX-poll having a finished eye or hole for the receptionof the helve.

l-leretofore attempts have been made to make ax-polls in this manner;but the sections of the bars have been such that they have beendifficult, if not impossible, of rolling and when rolled were notadapted to be shaped into a useful aX-poll.

The object of my invention is to overcome the defects of such priorexpedients and to provide means by which aX-poll blanks can be made byrolling in a cheap and eflicient manner.

I first roll a bar of steel of the shape in crosssection shown in Fig.2, having a thick middle portion 2 and side portions 3, which extendfrom the middle portion in opposite directions in substantially the sameplane, one side of the bar being formed with plain or fiat portions 4along the margin and with a curved surface between these flat portionsand a concavity 5 on the inner side of the middle portion 2. Such bar ofsteel is easily rolled without extra labor or cost. lVhen it is sorolled, I cut it transversely into blanks, as indicated by dotted linesin Fig. 1. I then take a blank formed in this way and bend up its arms 3toward each other, and when the flat portions 4 are brought in contact,as shown in Fig. 3, and welded, the aX-poll is completed. The section ofthe blank is such that the ax-poll is completely shaped by bending upthe sides of the blank. To this end the concavity 5 is of materialimportance, because if it were not present the eye of the ax would bemisshapen and would require special treatment to reduce it to properform.

By modification of the shape of the head 2 the bar may be adapted toproduce blanks for double-bitted axes or axes with heads of specialshapes.

The advantages of my invention will be appreciated by those skilled inthe art.

I claim A rolled bar substantially of the shape in cross-section shownin Fig. 2 and adapted to be divided into aX-poll blanks, substantiallyas and for the purposes described.

In testimony whereof I have hereunto set my hand this 9th day ofOctober, A; D. 1890.

CHARLES IV. HUBBARD.
